Abstract
UNLABELLED Chronic stress may produce a decrease in central NPY expression and subjects exposed to it may prove hypersensitivity to a novel stressor with dysfunctions in the NPY system and cardiovascular maladaptation to stress, even hypertension. Upregulation of NPY expression may contribute to successful behavioral adaptation to stress by reducing cardiovascular tone and suppressing anxious behaviors. Adaptogens, a new class of metabolic regulators stimulate NPY expression and release. The aim of this study is to increase tolerance and adaptation to stress of hypersensitive to novel stressor, occupational chronic stress exposed subjects with cardiovascular maladaptation to mild new stressor using adaptogens as part of prevention protocol. MATERIAL AND METHODS 40 military personnel with known cardiostressor reactional mode and occupational chronic stress exposure were exposed to mild novel stressor: occupational medicine routine evaluation and clinically assessed for maladaptative cardiovascular response prior and before application of 30 day prevention protocol. Employees were randomly split in two groups, one receiving standard prevention protocol (lifestyle counseling) plus adaptogens in multiple dose administration, twice daily and the other receiving only standard prevention protocol. RESULTS We found significant statistic differences in all cardiovascular parameters in adaptogen group and only in diastolic blood pressure in control group. CONCLUSIONS Adaptogens could be an important factor in successful prevention protocols of chronic occupational stress dysfunctions involving NPY systems.

Abstract
Adequate antithyroid drug treatment or surgery usually generates remission of myasthenia gravis (MG) in patients with thymus hyperplasia associated with Graves' hyperthyroidism. The case of a 46-year-old woman diagnosed with MG based on the clinical picture, anticholinesterase drug test and positive electromyography (EMG) is presented. The cervico-thoracic computer tomography revealed a compressive nodular goiter and normal antero-superior mediastinum and led to the diagnosis of MG secondary to the hyperthyroidism. An uneventful total thyroidectomy was performed, but postoperatively the MG symptoms worsened. TC99m tetrofosmin scintigraphy revealed an area of hyperfixation in the antero-inferior mediastinum, suggestive for thymoma, as confirmed by a repeated thoracic CT scan. Following a longitudinal sternotomy, a well incapsulated tumor of approximately 6/5 cm located in the antero-inferior mediastinum was found and an extensive thymomectomy was performed. The postoperative course was uneventful and the patient was discharged 9 days later with complete remission of myasthenia. The pathology report of the specimen revealed a mixt thymoma or AB thymoma after Muller-Hermelink and WHO classification, with invasive capsular foci corresponding to Masaoka II stadium. In conclusion, scintigraphy proved to be useful in the diagnosis and decision making of a thymoma.

Abstract
OBJECTIVE The calcium-sensing receptor (CASR) has an important role in calcium homoeostasis by controlling PTH secretion and renal calcium handling. Inactivating mutations in the CASR gene (HGNC ID: 1514) cause familial hypocalciuric hypercalcaemia (FHH). We present a case of FHH patient to describe a novel mutation in the CASR. SUBJECTS AND METHODS A 34-year-old patient was referred because of recurrent hypercalcaemia after resection of two hyperplastic parathyroids. Extensive evaluation found elevated PTH and low calcium/creatinine clearance ratio. One of her three children had high serum calcium concentrations. Genetic studies were performed by PCR amplification of CASR coding exons and direct sequencing of PCR products. Transient transfection of the wild-type (WT) CASR and the mutant CASR into COS-7 was performed to assess functional impact of the mutation and the capacity of either protein to mediate increases in cellular levels of inositol phosphates (IPs). RESULTS CASR sequencing found a previously undescribed heterozygous base substitution, determining a change of threonine to isoleucine at codon 550 (p.T550I) in the sixth exon. In contrast to those transfected with WT CASR, which showed a five- to eightfold increase in total IPs at high levels of calcium, COS-7 cells transfected with the (p.T550I) mutant showed no increase confirming to the inactivating nature of the mutation. COS-7 cells co-transfected with the WT and the (p.T550I) mutant showed an intermediate response suggesting a possible dominant negative effect. CONCLUSION This case report presents a not-yet-described mutation in the cysteine-rich region of the CASR extracellular domain, a mutation with a possible dominant negative effect.

Abstract
Ectopic ACTH secretion accounts for less that 10% of all causes of endogenous Cushing's syndrome. Carcinoids are rare thymic tumors, and when associated with ACTH hypersecretion display local or distant aggressive behavior. A 32-year-old woman was admitted to the Endocrinology Unit for obesity, moon face, facial hirsutism, hyperpigmentation, and secondary amenorrhea. Laboratory test confirmed the hypercortisolism and excess ACTH, while dexamethasone suppressive test was negative. Thorax computed tomography (CT) showed an antero-superior mediastinal tumor invading the pericardium and left mediastinal pleura. A complete resection through median sternotomy of the tumor, pericardium and left mediastinal pleura was performed. After a one-year symptom-free period, hypercortisolism recurred, confirmed by laboratory findings. Although no signs of local recurrence were seen on thorax CT, left internal mammary lymph nodes involvement and vertebral body metastases at C7 and LI were found. Refractory electrolyte disturbances could not be corrected resulting in severe cardiac arrhythmia and death from cardiac arrest. The reported case draws attention on the aggressiveness of ACTH-secralso due to the refractory electrolyte disturbances with fatal outcome.

Abstract
UNLABELLED Research on the relationship between iodine exposure and thyroid cancer risk is limited and the findings are inconclusive. OBJECTIVES Given this molecular data on iodine we decided to evaluate the changes of incidence and histology of thyroid cancer in the North-Eastern region of Romania (Moldavia) after the government decision from 2004 that introduced the universal iodination of alimentary salt. After this decision values of urinary iodine increased from 50 microg/L (2001-2002) to 117 microg/L (2006 -2008). MATERIAL AND METHODS We compared the incidence and the histology of thyroid cancer in residents living in an area known as a mild endemic goiter region (Moldavia-Romania) between 2001-2004 with the incidence and the histology of thyroid cancer between 2005-2008 in the same region after the introduction of universal iodization of alimentary salt. RESULTS The number of papillary cancers increased from 125 cases (2001-2004) to 276 cases (2005-2008). The number of follicular cancer decreased from 52 cases (2001-2004) to 27 cases (2005-2008). The ratio between papillary and follicular cancers increased from 4.80 / 1 (2001-2004) at 10.61 / 1 (2005-2008). The number of medullar thyroid carcinoma increased from six cases (2001-2004) to 24 cases (2005-2008). Thyroid anaplastic carcinomas number increased from 7 cases (2001-2004) to 12 cases (2005-2008). The total number of thyroid cancer has increased dramatically after the introduction of universal iodination of alimentary salt with 178% compared to 2001-2004 (from 190 cases in 2001-2004 to 339 cases in 2005-2008), despite the fact that the number thyroidectomies decreased from 1734 (2001-2004) to 1449 (2005-2008). CONCLUSION After the introduction the universal iodination of alimentary salt starting from 2004 the total number of thyroid cancers increased comparative with the period before universal iodination of alimentary salt.

Abstract
PURPOSE To evaluate and compare the impact on quality of life of tamoxifen and aromatase inhibitors (AIN's) in adjuvant settings, at women with breast cancer. METHODS From a total of 441 patients with breast cancer with hormonal treatment, were selected 177 of patients with adjuvant hormonal treatment (95 with tamoxifen treatment and 82 with AIN's treatment). These patients have completed the EORTC QLQ C-30 and EORTC QLQ BR23 questionnaires after 1 month of treatment (baseline), at 2 year of treatment with tamoxifen versus aromatase inhibitors (exemestane, anastrazole, letrozole). Mean change score from baseline and 2 years of treatment were compared in the both arms (tamoxifen vs. AIN's). RESULTS In both arms, after two years, a decreased QOL was observed as compared with the baseline. In the tamoxifen arm, global health status (GHS) and breast symptoms score (BRBS) were similar comparative with AIN's arm at baseline, with a similar status at 2 years measurement. CONCLUSIONS The global health status (GHS) and breast symptoms score (BRBS) shows that there is no difference in the QOL at the women with breast cancer treated with tamoxifen, comparative with the women treated with AIN's. We conclude that AIN's did not have an adverse impact on overall QOL, comparative with tamoxifen, in adjuvant settings.

Abstract
UNLABELLED Thyroid nodules are common, with up to 50% of the adult population having palpable nodules. With the use of ultrasound, up to 10 times more nodules are likely to be detected. Given this we decided to evaluate by retrospective study the incidence of thyroid nodule in the North-Eastern Region of Romania (Moldavia) between 2005-2009. MATERIAL AND METHOD We reviewed the records of patients admitted in the Department of Endocrinology, St. Spiridon Hospital Iaşi between 1.01.2005-31.12. 2009 (4712 patients) and with selected the cases with nodular goiter. RESULTS A total of 3105 cases of nodular goiter were identified. The women were most affected and highest prevalence was noticed for the patients with ages between 51-60 years. Most of the nodules were found in the right thyroidian lobe and the majority of the patients were euthyroid . The peak of incidence of nodular hyperthyroidism was different from that of diffuse hyperthyroidism. CONCLUSIONS Thyroid nodules are the most common endocrine problem and the increasingly frequent detection of nonpalpable thyroid nodules in asymptomatic patients requires new approaches for their management.

Abstract
UNLABELLED Thyroid ultrasonography is a simple diagnostic method for assessing the prevalence of goitre in children, parameter useful in the estimation of iodine supply. The normal limits recommended by WHO and ICCIDD (following the ThyroMobil study) have been debated by studies which found smaller values, even in regions included in the ThyroMobil study. AIM To assess the importance of the inter- and intra-observer differences in the determination of thyroid volume in children. MATERIAL AND METHODS Thyroid volume in 30 children was estimated using the rotating ellipsoid formula by 3 different observers. One of them determined twice the volume in 25 children. RESULTS Mean interobserver variations were 9.51 +/- 8.8%. More important differences were between observer 1 and 3. The differences between every diameter were between 12 and 16%, more important for the longitudinal one. The intraobserver differences were 6.29 +/- 6.12%. We did not find a relation between the value of the thyroid volume and the interobserver (r2 = 0.13, p > 0.05) or intraobserver (r2 = 0.15, p > 0.05) differences. CONCLUSIONS Interobserver variation may be important, and can partially explain the disagreements on thyroid volume in children. Intraobserver differences, although present, are less calculated. It is important to establish standards for each geographical area and, as much as possible, by the same person. In order to obtain comparable data the techniques of the ultrasound volume evaluation should be harmonized.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a frequent cause of infertility. Despite an impressive number of reports, few have evaluated the influence of age upon fertility. We present the outcomes of three infertile women with PCOS who achieved spontaneous pregnancies when ageing. CASE REPORTS Three patients with PCOS were monitored for more than 20 years. PCOS was confirmed by clinical data (oligo/amenorrhoea, infertility, hirsutism), hormonal measures and ovarian ultrasonography. All three infertile patients were treated for several years using numerous ovulation induction protocols with varying responses. When ageing, they gained more regular cycles and spontaneously became pregnant at 39, 40 1/2 and 36 years of age, more than 5 years after induction treatment was stopped, and in spite of increasing weight in each of them. CONCLUSIONS These clinical observations suggest improved fertility in some PCOS ageing women. The positive impact of ageing on cycle regularisation in PCOS has recently been claimed but the fertility outcome was not evaluated. Ovary ageing results in diminution of the follicular cohort in both normal and PCOS women, associated with decreased inhibin B and anti-müllerian hormone (AMH) levels. Lower inhibin B levels induce FSH enhancement, with a rise in FSH rate per follicle which may determine better follicle maturation, regular and ovulatory cycles in PCOS ageing women. The best proof of this improved fertility was the occurrence of spontaneous pregnancies which never occurred previously.

Abstract
UNLABELLED Fine needle aspiration biopsy (FNAB) in evaluation of nodular goiter generated a true revolution. It is generally assumed that the use of FNAB reduces the number of surgical procedures by 50%, while doubles the proportion of carcinoma in surgically treated patients. The aim of the study was to demonstrate the utility of FNAB in preoperative diagnosis of thyroid carcinoma. MATERIAL AND METHOD We have investigated 3240 patients with nodular goiter by FNAB (MGG stain and morphometrical analysis), followed by morphological examination in those who underwent surgery. RESULTS Globally, FNAB had a good sensitivity (77%) and specificity (95%), which made an accuracy of 92%, proving its diagnostic value. In follicular carcinoma (FC), where the cytological diagnostic cannot be certain, morphometry helped the diagnostic: mean cells diameter was significantly higher (p < 0.001) in FC (9.5 mm) vs. thyroid adenoma (8.6 mm). CONCLUSION With good statistical value, FNAB remain a useful preoperative diagnostic method.

Abstract
The technological revolution of the 20th century has changed not only the life style but also the human interrelations, including the physician-patient relationship. The old, primarily patriarchal, system (in which the patient trusted completely the physician and followed religiously his commandments) evolved into the current system in which the patient is an active partner in medical care. Patient education is increasingly recognized as an integral part of the therapy. The objectives of therapeutical education rely essentially in the improvement of the patient knowledge and skills concerning the disease and its treatment in order to harmonize his life style with the restrains of the illness. Therapeutical education must be complex, individualized, repeated, motivating, and controlled. In chronic diseases, both the health provider and the patient are in front of a permanent challenge. The educational process is in continuous movement, liable to permanent improvement.

Abstract
The aim of the study was to analyze several cases of secondary tumors to the thyroid, by focusing on the role of the immunohistochemical (IHC) exam in specifying the origin of the tumoral process. The studied group included 16 patients, investigated by fine-needle aspiration biopsy, frozen sections at the surgical moment, routine histopathological exam and immunohistochemical staining, using different antibodies, in accordance with the histological aspects. The final diagnosis was established as follows: metastases of squamocellular carcinoma with different degree of differentiation (seven cases), metastases of adenocarcinoma (four cases), metastases of renal cell carcinoma (two cases), metastases of Hodgkin (one case) and non-Hodgkin lymphoma (two cases). In four cases, the primary tumors were identified after the diagnosis of their metastases in thyroid. The immunohistochemical staining was useful in the diagnosis of squamocellular carcinoma metastases, poorly differentiated (CK19 positive), of renal cell carcinoma with clear cells (CK18, CK19 and CD10 positive) and in the establishing of the tumoral origin for adenocarcinomas (CK7 positive--respiratory tract, CK20 positive--digestive tract). Secondary tumors to the thyroid are rare tumors, with miscellaneous histological aspects, reason for which the diagnostic may be difficult. In these cases IHC is a useful method, allowing to the identification of the primary tumor.

Abstract
Fine needle aspiration biopsy (FNAB) of the thyroid is limited in distinguishing hyperplastic nodular goiter from true follicular neoplasm and in separating follicular adenoma from follicular carcinoma. The present study was done to evaluate if the morphologic and morphometric investigations and silver staining of nucleolar organizer regions (NORs), either alone or in association would help to differentiate the thyroid follicular diseases. 40 FNAB smears of thyroid follicular diseases, histopathologically diagnosed as nodular goiter, lymphocytic thyroiditis, follicular adenoma and follicular carcinoma, were analyzed using the standard cytological exam, quantitative analysis and NORs assessment. The qualitative evaluation, correlated with the numerical results obtained from the quantitative analysis, revealed that the cellular pattern, mean nuclear diameter and NORs area are valuable criteria in the diagnosis of the benign and malign follicular lesions, respectively. The results attained through morphometry increase the sensibility and the specificity of FNAB in the diagnosis of thyroid follicular carcinomas.

Abstract
The most common clinical presentation of differentiated thyroid cancer (DTC), consisting of papillary and follicular adenocarcinoma (with their histological variants), is the solitary thyroid nodule. A review of the literature is performed in order to describe particular forms of DTC, in terms of incidence, diagnosis and treatment: occult carcinoma, carcinoma on aberrant thyroid tissue, "functional" thyroid carcinoma and familial non-medullary carcinoma. A particular interest is shown to the coexistence of malignancy with benign thyroid diseases, such as goiter, hyperthyroidism and Hashimoto's thyroiditis, as well as parathyroid adenoma. In conclusion, the authors emphasize that the association of carcinoma with benign thyroid conditions is not rare and it substantiate an aggressive approach in regard to diagnosis and treatment, increasing the indication for surgery and, moreover, for total thyroidectomy.

Abstract
Differentiated thyroid cancer (DTC), including papillary and follicular carcinoma with histological variants, has an excellent prognosis; nevertheless a subset of these tumours is clinically aggressive and, in some patients, fatal. Treatment of DTC remains controversial, regarding the extent of primary surgical resection, the need for lymph node dissection and the role of postoperative radioactive iodine ablation. In addition to the widely accepted TNM classification, recognition of significant risk factors and developing of staging systems, such as AMES, AGES, MACIS, MSKCC and NTCTCS, has helped to identify the patients with a potential aggressive course of the disease and high risk of recurrence. This has allowed the development of a rational and selective approach to therapy, thus, avoiding excessive treatment and subsequent morbidity without compromising the oncological outcome.

Abstract
PURPOSE Determination of ioduria in order to establish the actual degree of iodine deficiency in school-age children from 4 counties in Moldavia. MATERIALS AND METHODS Urinary iodine was determined in 927 school-children aged 7-14 years from 4 counties: Suceava, Iaşi, Neamţ and Botoşani. The determination was made by cerium-arsenate method and by a semi-quantitative method. RESULTS The median value of ioduria was 3 micrograms/dL in Suceava, 8.8 micrograms/dL in Iaşi, 7.1 micrograms/dL in Botoşani. In Roman-Neamţ 93.75% of all samples had a value of ioduria below 10 micrograms/dL. From this point of view, Suceava and Roman are with moderate iodine deficiency; Iaşi and Botoşani are with mild iodine deficiency. CONCLUSIONS Despite the existence of a program of iodine prophylaxis, there are still many regions in Moldavia with iodine deficiency, so it is important to have more measures of sanitary education and prophylaxis in these regions.

Abstract
Prolactin is a polipeptidic hormone secreted by the anterior pituitary gland, whose main role consists in the stimulation of lactation in the postpartum period. The increasing of prolactin secretion can be physiological (pregnancy and lactation) or pathological (hypothalamic and pituitary diseases, iatrogenic, etc.). The suppression of the hypothalamic-pituitary-gonadal axis and the resistivity of the ovary and gonadotropin action are induced in hyperprolactinemia, the amenorrhea and lack of ovulation being the result. Infertility associated with hyperprolactinemia is reversible with treatment, irrespectively to the type of treatment (radical or medical). Lowering of prolactin levels to normal or near normal is often necessary to permit ovulation. Dopamine-like drogs, as bromocriptine, appear to be safe for the developing fetus, at lest when the treatment is interrupted in the first trimester of pregnancy.

Abstract
Ultrasonography is a useful tool in diagnosing and monitoring thyroid pathology. The aim of this study was to evaluate the value of thyroid ultrasonography in the follow-up of subacute thyroiditis (SAT). The study group included 48 subjects with clinical and biological diagnosis of subacute thyroiditis. All patients were evaluated by ultrasonography and followed-up for a mean period of 12 months. The evaluation protocol included biological data (TSH, T4, erythrocyte sedimentation rate--ESR) and ultrasonography, performed at 1, 2, 3, 6, and 12 months. Initially, all patients had an enlarged thyroid volume (median = 30.5 ml, range 23-90) and a low echogenicity, with an inhomogeneous aspect in 54.1% cases. After a mean period of 3 months thyroid volume had a significant reduction (median volume = 20.2 ml, range 7-36, p < 0.0001). Echogenicity was also significantly improved, with a decrement, on a semi-quantitative scale of 4 degrees (1 = normal, 4 = intense hypoechogenicity), from 3.25 to 2.48 (p < 0.0001). Almost half of the patients (45.8%) presented persistent (although slighter) hypoechoic/inhomogeneous pattern. Ultrasonographic abnormalities were not correlated with the intensity of the inflammatory syndrome and/or the thyroid status. Recurrence appeared in 10 (20.8%) patients. All patients presented a new thyroid enlargement (from a median = 16.1 ml to 31.5 ml, p = 0.056) and an extension of hypoechoic regions. The risk of recurrence could not be correlated with thyroid function, inflammatory syndrome or ultrasonographic aspect. There were not significant differences between the subgroups of patients with and without recurrence concerning the initial thyroid volume (p = 0.889), echogenicity (p = 0.735), TSH (p = 0.321) or ESR (p = 0.1332). Thyroid ultrasonography is useful not only for the initial diagnosis but also for the follow-up of patients with subacute thyroiditis. Remission and recurrence can be appreciated and monitored by the ultrasonographic pattern of the thyroid.

Abstract
Prolactinoma is a frequent endocrine cause of infertility in both man and women. The aim of this study was to evaluate female fertility in association with hyperprolactinemia. The study is a retrospective one, based on the cases monitored in the Endocrinology Department of Iaşi. From the 113 cases of prolactinoma in women we have selected 83 women aged between 18-45 years (fertile age). The diagnosis was suspected on clinical bases: endocrine (amenorrhea-galactorrhea, associated or isolated, spaniomenorrhea, infertility), and tumoral (headache, visual disturbances) syndromes and confirmed by biological (PRL dosage) and morphological (pituitary CT) tests. We classified the found associations between prolactinoma and fertility in: no correlation (previous pregnancies with no desire for another child--76 patients = 75.2%); prolactinoma diagnosed immediately after a pregnancy by persistency of galactorrhea, lack of menses reapparition, headache (16 cases = 15.8%); prolactinoma diagnosed before pregnancy, which was obtained thanks to the hyperprolactinemia treatment (9 patients = 8.9%). All 9 patients of the last group were in remission at the moment of pregnancy apparition and had a normal pregnancy, giving birth to normal children. Infertility associated with prolactinoma is reversible with treatment. Lowering of prolactin levels to normal is often necessary to permit ovulation. Bromocriptine used by pregnant women appears to be safe for the developing fetus, at least in our study where the treatment was interrupted in most cases in the first trimester of pregnancy.

Abstract
Alopecia areata is a dermatological disease, characterized by the loss of hair, which affect men, women and children and can evaluate alone or in association with a variety of other disorders. Between these endocrinological diseases, especial thyroid disorders, have a high incidence. Twenty-seven patients with alopecia areata (12 women and 15 men) aged between 3 and 46 years were endocrinologically investigated. Eighteen of them (66.6%) had endocrinological disorders. Thyroid diseases were present in 10 cases (37%): 4 cases with endemic goiter, 2 cases with nodular goiter and 4 cases with hypothyroidism (1 case with autoimmune thyroiditis, 1 case with nodular goiter, 1 case with cystic goiter and 1 case with hypothyroidism post thyroidectomy for thyroidal lymphoma). Twelve cases (44.4%) were found with tetania. The incidence of thyroid diseases in alopecia areata is higher then in general population (2%), as well as the incidence of tetania. These evidences suggest that it is necessary to make a screening of endocrinological disorders in patients with alopecia areata.

Abstract
Levothyroxine (LT4) treatment in benign thyroid nodules is a controversial management. The favorable response varies between 10-60%, being, in some studies, comparable between treated and untreated groups. The aim of this study was to evaluate the response of uninodular goiter at the LT4 treatment, in comparison with untreated patients. The study group (S) included 53 patients diagnosed with nodular goiter, treated with LT4 for 1 year. 26 patients with nodular goiter, age and sex-matched, untreated, constituted the control group (C). All patients were from a minor iodine deficient area. The including criteria were euthyroidism, single nodule, solid (ultrasonography), cold (Scintigraphy), and benign (FNAB). After 1 year mean nodular volume had a significant decrement in both groups, higher in group S (35%: from 7.8 to 5.2 mL, p = 0.0098) than in group C (25%: from 8.4 to 5.9 mL, p = 0.026). Linear regression showed a slight correlation between the nodular decrement and the initial volume (r = 0.23): the responders percentage was higher in nodules with a volume < 5 ml than in those with volume > 5 ml (51.5% vs o 19.6%, p < 0.0001). The evolution of treated nodules seamed to be better than of the untreated ones, but the differences were only slightly significant. We believe that the evolution of thyroid nodules under LT4 treatment can be influenced by the iodine supply, since in most of the studies from minor iodine deficiency regions (Europe, South America) the response is better than in regions with sufficient iodine supply (North America). Knowing the potential side effects of LT4 therapy, this kind of management of benign thyroid nodules should be reserved to selected cases.

Abstract
Relationship between weight and hypothalamic-pituitary-ovarian axis has been long time studied. Underweight female patients can have or not disturbances of gonadal system and the importance of the weight or body composition in the mechanisms of these abnormalities is not clear. In our study, we have investigated body composition in 15 underweight female patients. Five patients have had anorexia nervosa, with amenorrhea (group AN), and other 10 patients were eumenorrheic, but with low body weight (hypoanabolic syndrome--group HA). Bioelectrical impedance method was used to investigate body composition. Total body water (TBW), lean mass (LM), and fat mass (FM) were determined. Nutritional status was also assessed using body mass index (BMI). The mean body weight was significantly decreased (p = 0.05, 36.6 +/- 4.68 Kg versus 44.1 +/- 4.67 Kg) in group AN as compared to group HA. Fat mass was very low in group AN (9.45% of body weight versus 11.3% of body weight in group HA), but there was not significant difference. Lean mass was significantly decreased in group AN (33.24 +/- 2.37 Kg) in comparison with group HA (39.3 +/- 4.06 Kg). Correlations between anthropometric indices were studied. Positive significant correlations were obtained between body weight and lean mass, total body water and basal metabolism in both groups. In conclusion, our study reveals that body weight has a relative importance in ovarian axis dysfunction, and the most important of body compartments seems to be lean mass.

Abstract
First described in 1935, polycystic ovary syndrome (PCOS) is a frequent endocrine disease (6% in female population). However its pathogenicity is not yet completely understood. The possible etio-pathogenic mechanisms include: neuroendocrine disorders (hypothalamic, as a result of congenital androgenism or of disorders of neurotransmitters or pituitary, with excess of LH), ovarian disorders (enhanced sensibility at LH, local growth factors, hyperactivity of Cit P450cl7 alpha enzymes), adrenal disorders, insulin resistance, genetic determinism, puberty onset. The authors discuss in detail this hypothesis and these possible importance.

Abstract
The difficult diagnostic and therapeutic management of patients having gastrinoma with multiple endocrine neoplasia type I (MEN I) has been discussed by reference to the literature and a personal experience of 2 patients with Wermer syndrome. The syndrome is often familial and might be inherited as an autosomal dominant trait with a high but variable degree of penetrance. Pancreatic islets, parathyroid glands and adenohypophyseal [correction of antehypophyseal] cells are the three localization main for endocrine involvement in MEN I syndrome.
